A Wavelet Transform Based Feature Extraction and Classification of Cardiac Disorder

Abstract: This paper approaches an intellectual diagnosis system using hybrid approach of Adaptive Neuro-Fuzzy Inference System (ANFIS) model for classification of Electrocardiogram (ECG) signals. This method is based on using Symlet Wavelet Transform for analyzing the ECG signals and extracting the parameters related to dangerous cardiac arrhythmias. In these particular parameters were used as input of ANFIS classifier, five most important types of ECG signals they are Normal Sinus Rhythm (NSR), Atrial Fibrillation (AF… Show more

“…All four types of wavelets have been used in biomedical signal and image processing [15][16][17][18][19]. Symlet functions have the disadvantage of generally slower processing than other wavelet-based methods including Daubechies filtering [13][14][15][16][17].…”

“…Mustafa et al [18] used EMD to analyze anesthesia EEG signals to extract the time-frequency features in the delta-theta bands. Sumathi et al [19] employed the Symlet wavelet transform to extract the attenuation factor and basic frequency parameters of the ECG signals for cardiac arrhythmias. Sen et al [20] studied 41 feature parameters from 20 attribute algorithms in four categories.…”
